Problems With Customizr Theme and Table Maker Plugin

I am using a plugin called Table Maker (https://wordpress.org/plugins/table-maker/) to create a comparison table for my website.

When I try and set the table’s header color, it doesn’t work. I have contacted the Table Maker folks and they indicate that it is Customizr that is overriding their colors.

I have an example at https://techreational.ca/motorhome-points-of-inspection/ The table’s header is supposed to be blue, but it isn’t. If I edit the CSS and add !important to the background-color for the table header row, then it shows up.

If I switch to different themes, the color shows up just fine in the table header row.

Could you please look into this? I’d love to continue using Customizr, but this is becoming a deal breaker for me.

I’ll be glad to provide any more info as required to help resolve this issue.

Thanks for any help.
